Effect of Seed Rate and NPK Fertilizer on Growth and Yield of Wheat Variety Punjnad-1

M.S. Cheema, M. Akhtar and Liaquat Ali    

Abstract: The study was conducted for two consecutive crop seasons at Agronomic Research Station, Bahawalpur during Rabi 2000-2001 to 2001-2002 to evaluate maximum yield potential of wheat variety punjnad-1 as affected by various seeding rates 75, 100, 125 and 150 kg ha-1 and NPK levels 0-0-0, 100-50-0, 150-100-50 and 200-100-50 kg ha-1. Maximum wheat grain yield of 4293 kg ha-1 was recorded with fertilizer, level of 150-100-50 NPK kg ha-1 with seeding rate of 125 kg ha-1. It was closely followed by same fertilizer level with seeding rate of 100 kg ha-1 by giving 4287 kg grain yield ha-1 which showed that equally good results were obtained with fertilizer dose of 150-100-50 kg ha-1. It showed that higher dose of NPK fertilizer induce more tillering and grain weight in wheat plants under low seed rate which compansate reduction in grin yield. In both seasons increasing fertilizer levels NPK upto 150-100-50 kg ha-1 with seeding rate of 75, 100 and 125 kg ha-1 significantly and linearly enhance wheat grain yield while reduction in yield was obtained beyond this fertilizer dose and seeding rate.
